TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Oct. ".7, 1919.

original application filed October 31, 1916, Serial No. 128,670. Dividedand this application filed December To all whom it may concern:

Be it known that I, JOHN WALDI-IEIM, a

citizen of the United States, residing in Elizabetlu'in the county ofUnion and State of New Jersey, have invented certain new and usefulImprovements in Type-Writing Machines, of which the following is aspecification.

My invention relates to typewriting machines, and more'particularly to atabulating mechanism; and is a division of my c0- pending applicationSerial No. 128,6?0, filed October 31, 1916.

A feature of the present invention is the provision of a key-set deviceto be used for selectively setting the machine for columnselecting work.

The stops for column-selecting are, according to the preferred manner ofpractising my invention, set individually in any one of a plurality ofeffective positions, transversely of the stop-bar, so that, withsuitable mechanism to cooperate with the variously adjusted columnstops, the car riage may be arrested at any selected columnar positionor zone.

An additional feature of the invention is that the carriage may bearrested at any selected decimal point inany selected column or zone.

The key-set column-selecting stop device includes a column-selecting stofor each letter-space position of the carnage, and akey-controlledprojector for selectively moving the column-selecting stops to eflectivepositions. Preferably, there is provided a plurality of keys in thekey-board for moving the projector through difierent dis-' tances. e

Other features and advantages will hereinafter appear.

-The typewriting machine is of theregular Underwood construction, ofwhich typebars 11 swing upwardly and rearwardly to print against acylindrical platen 12, which rotates on an axle 13, in a carriage 14,which is driven from right to left of the machine by a spring drum 15,connected thereto by a strap 16. The letter-space movements .of'

the carriage are controlled by a suitable escapementmechanism having forthis purpose a normally engaged rack 17, which meshes with a pinion 18,connected to the escapement wheel 19, the latter engaging with thereciprocating dogs 20, which are actuated during'printing operations bythe type-bars 11 and a universal bar (not shown). I

To indicate the letter-space position of the carriage, there is provideda pointer 21, on the carriage 14, to cooperate with a scale 22, thelatter being fixed on the frame 23 of the typewriting machine.

A decimal tabulator may be provided, as in my co-pending applicationherein referred to, which may comprise denominational stops 29 at theupper vend of plungers 28, which may be moved by suitable keys (notshown) into the path of a column stop 30 carried by a stop bar 31; thelatter being secured to the typewriter carriage by brackets 32.

The carriage may be released during tabulating operations by theplungers 28 which engage with suitable mechanism, shown in my co-pendingapplication herein mentioned, to lift the rack 17 against the tension ofa spring 40 out of engagement 7 with theiescapement pinion 18. After thedisengagement of the rack 17 from the pinion 18, the carriage is free torun from right to left of the machine, under the influence of the springdrum 15, until it is arrested by one of the column stops 30, en,

gaging with the actuated denominational stop or coiiperative stop 29.

The key-set mechanism comprises a key 50, and a second arm 51 locatednear the center of the machine. The upper end of the plunger-47 isprovided with a finger 52,

' the relative position of which, with respect to the denominationalstops, is as indicated in Fig. 4.

The column stops, of which there is one on the stop bar" for eachletter-space position, are normally in their uppermost popointer 21 andscale 22, at any desired sitions. When it is desired to set anysele'cted column stop to an effective position, the carriage is locatedby means of the columnar position or zone, thus locating the selectedcolumn stop under the finger 52. The key 43 is then actuated, to movedownwardly the stop-setting element or plunger 47, thus moving, by meansof the finger 5 2,

the column stop 30 to an efi'ective position.

'To restore the stops 30 to their ineffective or neutral position onsaid bar, which is necessary before setting up a new combination ofstops, there is provided on'the stop bar 31 a manually-controlledstop-restoring slide 53 (Figs. 1 and 4), which is moved leftwardly onthe stop bar, against the tension of a spring 54, to cause an upwardmovement thereof, by means of shouldered.

screws 55 and cam slots 56. A stop-engaging portion 57 of the slide 53underlies fingers 58 of the'stops 30; thus, when the slide movesupwardly, the set column stops are moved therewith until arrested by asecond finger 58 formed near the lower edge of the stops- 30, andcoiiperating with the under side of the stop bar 31.

To hold the stops 30 in any position to which they may be set, there isprovided for each stop a spring-pressed ball 59, which drops intonotches 60 formed on the stop'30.

I have provided several keys 43 to cotiperate with the lever 44, to moveit selectively through. different angular distances, thus transmittin avariable movement to the finger 52 o the stop-setting element 47, to setany one of the stops 30, selectively, to any one of a plurality ofpositions transversely of the stop bar. The keys 43 are provided withkey-stems 61, which are guided in suitable slots formed in a U- shapedplate 62, secured to the lefthand side of the machine frame 23 (Fig. 2),in

The stems 61 engage with bent-off fingers" 66, on the lever 44, to movethe latter through different distances, there being a lost-motionbetween some of the stems and their cooperating. fingers for thispurpose. In the drawings, I have shown four keys;

thus, any stop 30 can be setto any 011601 four positions, the positionof the latter being dependent upon the key depressed. The 'fourefiective positions of the-column stops 30 are indicated in Figs. 1, 2and 4. Referring to Fig. 4, it'will be seen that the stops are set, fromleft to right, in the first, second, third "and fourth columnarpositions. It will also be seen that the lower ends or engaging portionsof these stops are arranged in stepped relation with respect to eachother. It will further be seen, that by varying the normal positions ofthe 006perative or denominational stops 29, and with suitable mechanismused to move the denominational stops through the same distance, whenactuated by their respective keys, any one of the denominational stopscan be brought selectively into engagement with any one of the setcolumn stops, as disclosed in my co-pending application hereinmentioned. The plungers 28 are arranged so that they may be raised orlowered for this purpose by suitable column-selecting mechanism, (notshown), to bring the denominational stops 29' into effective relationwith any one of the set column stops.

The column-stop-bar31 (Figs. 3 and 4) comprises two parallel bars 101and 102, between which are held the column stops 30, in suitable slots.The two parallel bars are separated from each other, and held inrelative position, so that the slots in which the colunm stops move arein perfect alinement, by T-shaped members 103, one at each end of thestop-bar 31. The stop-bar is held assembled by screws 104, which passthrough holes in the bar 101 and the members 103, and are threaded intothe bar 102.

To give a brief description of the sequence of the operations of myinvention, let it be,

assumed that all of ighe column stops 30. are in their uppermost rneutral position, on the stop-bar 31, in which position none of thestops are eifective.

Starting with the carriage at the extreme right, it is now'moved in aletter-space direction until the first columnar position is reached. Thecolumn1key of the key-set de- I vice is nowactuated, thus settingacolumn stop to the second uppermost position, by nieans of the finger52, on the stop-setting element 47 ('Fig. 5). The key-set mechanism isnow restored to its normal position by the spring 46, acting on the keylever 44, and oneof the springs 64, acting on the key-stem 61. This sameoperation is repeated, when the carriage is moved to the second, thirdand fourth cOlumnar positions, by depressing the column 2, column 3 andcolumn 4: keys, respectively, (for the last position see Fig. 6). Thusthe column stops are set, each with its engaging portion in a lowerlevel than the previously set column stops.

The column stops have now been arranged on the stop-bar, as indicated inFig. 4, and i the machine is ready for column-selecting.

For this purpose, let it be assumed that the denominational stops 29 arein their lowermost effective positions. If one of the tabulator keys isnow actuated, the denominational stop 29 will be raised into the path ofthe column stop 30, in the fourth columnar position. The carriage is atthe same' time released, to permit the column stop 30 to en gage withthe denominational stop 29; the

latter will at this time be out of range of" the column stops, in thefirst, second and third columnar positions. The denominational positionin the column at which the carriageis arrested is dependent upon thetabulator key actuated. If, after again returning the carriage to theright, it is now desired to position the carriage in the first columnarposition, the denominational stops are moved to theiruppermosteiit'ective positions, so that when they are actuated by their keys,they will be brought into the path of the first set column stop on thestop bar. In a like manner the carriage may be positioned in the secondand third columnar positions by first setting the denominational stopsto their proper effective positionsby the column-selecting mechanism.

It should be understood that, although I have shown only fourstop-setting keys, a greater number may be employed.

Variations may be resorted to within the scope of the invention, andportions of the improvements may be used without others.
